Fig. 6From: Extract of Bletilla formosana callus elevates cellular antioxidative activity via Nrf2/HO-1 signaling pathway and inhibits melanogenesis in zebrafishMelanogenesis inhibitory effect of B. formosana callus extract in α-MSH-induced B16F10 mouse melanoma cells. A Cell pellet collection. B Relative intracellular melanin content. C Relative extracellular melanin content. The results were normalized with BCA. Data are presented as means ± SD of triplicate experiments. *p < 0.05, **p < 0.01, and ***p < 0.001 compare with control. # p < 0.05, ## p < 0.01, and ### p < 0.001 compare with α-MSH-treated groupBack to article page
